Abstract

Cilindro hidráulico para brazos telescópicos.
Cilindro hidráulico para brazos telescópicos, especialmente para brazos de grúas, que comprende una camisa (1) cerrada mediante tapas extremas (2) y (3), un émbolo interno (4), que delimita cámaras de expansión (5) y retracción (6), un vástago tubular (16) asociado al émbolo, que sobresale a través de la tapa (3) y queda cerrado por una cabeza (17), que es portadora de un pistón de pilotaje (21). Por el interior del vástago tubular (16) discurre un tubo (18), parcialmente desplazable por la acción del pistón (21). La tapa (2) lleva fijada en la boca de entrada un conducto (11) portador de un casquillo (14) desplazable por empuje del tubo (18). El conducto (11) y tubo (18) dispone en su pared de orificios (13').
